Abstract (en)

[origin: EP0722811A1] A robot which requires no electric wire (power transmission wire and signal wire) connecting respective joint shafts. A high frequency electromagnetic induction electrodeless power transmission unit and an optical transmission or high frequency electromagnetic induction signal transmission unit are installed in a reduction gear that is coupled to an electric motor shaft for driving the respective shafts or a direct drive electric motor so that a power or signal wire is pulled out through a groove or a hollow portion of an output shaft of the reduction gear or the direct drive electric motor. In addition, information beyond the output shaft is fed back on a signal wire that is pulled in through the groove or the hollow portion of an output shaft. <IMAGE>
